Abstract
Condensed pyrazole 3-oxo-propanenitrile derivatives of formula (I) ##STR1## wherein X represents a --CH(R.sub.4)-- group, an oxygen atom or a --S(O).sub.n -- group where n is 0, 1 or 2; R.sub.1 represents C.sub.1 -C.sub.6 alkyl, pyridyl or unsubstituted or substituted phenyl; R.sub.2, R.sub.3 and R.sub.4 are as defined herein; and Q represents hydrogen, carboxy, C.sub.2 -C.sub.7 alkoxycarbonyl or a --CON(R.sub.a)R.sub.b group, R.sub.a and R.sub.b being as defined herein; and their pharmaceutically acceptable salts have immunomodulating activity and can be used in particular as immunomodulating agents, e.g. in the treatment of acute and chronic infections of both bacterial and viral origin, alone or in association with antibiotic agents, and in the treatment of neoplastic diseases, alone or in association with antitumoral agents, in mammals.
